A Game Theoretic Approach to Setting the Pilot Power Ratio in Multi-User MIMO Systems.
IEEE Transactions on Communications(2018)
摘要
We consider the uplink of a single cell multi-user multiple input multiple output (MU-MIMO) system, in which the base station acquires channel state information at the receiver by means of uplink pilot signals. Since each mobile station has a sum power budget that is used to transmit pilot and data symbols, the pilot power ratio (PPR) has a large impact on the system performance in terms of spectr...
